To azl whomit may-concern." Be it known that I, JOHN C, SP NCER, a citizen of the United States, residing at Spieeland, in the county of -Henry tate of Indiana, have invented certain new and useful Improvements in Shade-Roller @011- trolling Means,-'o;:t--wh ich the following is a specification, reference being {had to the accompanyingdrawings' invention relates to Window shade fixtures and more particularly "to' means for controlling the movementot'a shade roller.

1t is an obj ect, oi? the I invention to provide means of this character which permits an operator to regulate the rotation of the shade 'rol lefby the spring so that the shade *mayxjnstantly be adj-ustedand'held exactly movable support to which shade brackets are connected, theshadeibrackets supportthe usual spring operated shade I roller, pawlmechariism carried by one of said "brackets for engagement with the shade roller, and a handle anda trigger carried by the movable support in spaced relation to the :pawl mechanism for releasing and stopping the rotation of the shade roller when desired in the adjustment of the pint itain; and wherein said p aWl- -i nechan ism provides a positive "locking device which preventslac'oidentalrotation of-the roller.

' ,It is still a further object of the inven- ,;tion t0 provide 'means' of'this character eluding a shade having a rod secured to oneend to which a curtain or shade cord is-detachably mounted, the cord serving to support the shade over the window, the-opposite end of the curtainor shade'b eing connectedto a rollercarried 'by'a movable support, whereby the length of the shade maybeincreased or decreasedby operation or the roller,,.=and the window shade in its adjusted position moved longitudinally of theiwindow by the curtain. cord.

r-nea is, the; sha de'bei'ng removed; Fiig ure 4 1s a section taken onr i'of lilgurefipand a the shade-ro' ller is controlled. Refer-ring {to I the v 9 design-ates spring 316.- A pintle or" tifiunnion l8 invention consists in the improved constructlon and arrangementof parts'to be hereinafter more particularly described, fully claimed and illustrated in the accompany-- ing drawings, in which F1gLlIfQ-1"1S a view in elevation of a =W1-Ildow shade showing the controll ng" means applied; Y t Figure 2' is asideelevation of the structure shown in {Figure 1 Fi-gure'ii is a plan viewof the controlling Fig-ure 5 is detailed view of theleol-lar "he fline v or drum, by means efwhieh the grotation{of a supporting member of any desired "matecured to --eaeh end portion vo f itl-l'e bar and y projecting at right" angles to said bar are 'sha'debrackets *l O an-d" 11. it gisofcourse l obvious that these brackets maybe adjusted the brackets 10 and -'1 1,;sa id roller including the us-ual hollow end portion 15. Disk posedwith in said hollow end portion is a from theend-portion '15, seidpintle ed {to extend through {the some, The pinsubstantially flat or rectangular and adapt Y tle is secured orconnected to a shaft 19 -aroundwhioh the spring '16 is wound to permit rotation of the roller 14; independently of the .pint'le. jFllhe end portion 15 is register with an openin'g 22 carried by the pintle '18 sothatwhen the shade is being nail is removed when the roller is engaged with the brackets, to permit rotation of the spring and is inserted in I said openings to -prevent rotation-of the spring" when -the roller is ;I ernoved -fron1 the brackets.

Carried by -thebpposite end of roller'is a'c ap or ferrule 24, hile extending -from said end of the roller is stub 1 shaft-25. Theshaft'25 has its end portion "With th, eseand other objects in view, the i,

26 substantially flattened and inserted in the provided; with anopening-ZOadapted to the end 23 of the roller. A. nail 27 or like fastening means is inserted through the forrule and through an opening 28 provided in the end portion 26 of the stub shaft to prevent rotation of said shaft independently of the roller. The end portion 29 of the stub shaft is substantially round so as to permit rotation of the shaft relative to the bracket 10, while disposed adjacent the end portion 29 the stub shaft is a collar or drum 30 having a plurality of openings or recesses 31.

in its periphery. It will thus be seen that by this arrangement the pintle 18 is pre vented from rotation, while -the stub shaft 25 is adapted to rotate with the roller.

In order to render the locking action and the adjustment of the shade roller more positive and accurate than was possible heretofore, there is provided a novel controlling .ed opening 36 in its intermediate portionadapted to receive a stud or finger 37'. The stud or finger 37 is adapted to project through the slot 33, while a tooth is adapted to project through the forward end of the casing'and into one of the openings 31 so as to control movement of the roller 1 1. Disposed between the end of the bracket secured to the support and the rear end of the pawl 34 is a coil spring 38. By disposing the casing 32 adjacent the foot or end of the bracket 10 it is not necessary to close the rear end of the casing, as it is possible for the spring to engage the" bracket. The spring is intended to normally urge the pawl outwardly of the forward end of the easing into engagement with the collar or drum 30.

In order to manually control the operation of the pawl without requiring the operator to go to the end of the roller to adjust said pawl, there is provided a handle member 89 which is secured to the intermediate portion of the, movable support 9 substantially in a horizontal position, said handle being stationary or rigid.v Pivoted to the handle 39 is a trigger 40 adapted to move laterally of the handle and having an opening 4-1 in its upper end. Pivoted to the top of. the support 9 adjacent the foot of the bracket is abell crank lever 42, the end said lever being connected by a .con-

cting member extending through the opening 41. The end of the bell crank ing cord 49 is secured at its ones to the bar 4:8, llllG covered by clips 50.

securing means being protected and A ourtaln cord 51 has one end formed into a loop adapted to engage the balancing cbrd 49, said loop being slidable longitudinally of the cord 49 so as to balance the shade upon adjustment of the cord 51 by the operatorn p The cord 51 is arranged to extend over a lock pulley 53 of conventionalform, said pulley being carried by the upperv portion of the window casing so that when desired the cord may be locked in the pulley to hold the shade in the desired adjusted position.

in operation, when it is desired to adjust the shade over the window, the cord 51 may be released from its locked position. and the entire shade including the roller and the support moved longitudinally ofthe window tothe point desired. If the shade. is not long enough, it may be readily adjusted by grasping the. handle 39 and operating the trigger 4-0 so as to cause release of the pawl 84 and permit the shade roller to rotate through the medium of the spring 19.. This adjustment may be made without releasing the curtain cord 51. ,When the trigger 40 is released the roller is instantly locked and prevented from accidental rotation regardless of the movement of the shade by the cord 51. v j I From the foregoing it will be readily seen that this invention provides novel means for controlling a shade roller which may be operated independently of the curtaincord of the shade to decrease or increase the length of the shade and wherein the roller may be moved bodily with the support and curtain by the curtain cord. In addition to this, the support of the brackets is also utilized to carry a part of the controlling mechanism. It is therefore possible to position the trigger for operating said mechanism centrally of the shade roller and within conveniently reach of the operator so that the shade roller may be instantly adjusted. Furthermore the possibility of vibration causing accidental rotation of: the roller. is eliminated. I i

What is claimed is 1. A shade fixture of the character described embodying a support arranged to move longitudinally of a window casing, brackets carried by and projecting outwardly from the support, a spring actuated shade roller mounted between the brackets, a spring pressed pawl'carried by one of said brackets adjacent one end of the roller, a

handle member projecting from the intermediate portion of the support, a trigger carried by said handle, and means operatively connecting the trigger to the spring pressed pawl for releasing the pawl and permitting rotation of the roller through the medium of the spring.

2. Means for controlling the movement of a shade roller embodying a movable support, brackets projecting from said support, a shade roller rotatably mounted upon said brackets, a casing carried by the inner face of one of said brackets, a pawl disposed Within said casing, a finger carried by said pawl and projecting through the slot provided in said casing, aspring disposed bee tween said pawl and the foot ofsaid shade bracket, said pawl being adapted to opera tively engage a ratchet member carried'by one end of the roller, a bell crank lever carried by the support adjacent the pawl, a

means for operatively connecting the pawlto one end of the bell crank lever and the opposite end ofthe bell cranklever to the trigger.
